TLDR
The elaborate mechanisms regulating chromatophores in these lovely aquatic animals are described and it is indicated that some paracrine factors such as endothelins (ETs) are involved in these processes.Abstract:
Chromatophores, including melanophores, xanthophores, erythrophores, leucophores and iridophores, are responsible for the revelation of integumentary coloration in fish. Recently, blue chromatophores, also called cyanophores, were added to the list of chromatophores. Many of them are also known to possess cellular motility, by which fish are able to change their integumentary hues and patterns, thus enabling them to execute remarkable or subtle chromatic adaptation to environmental hues and patterns, and to cope with various ethological encounters. Such physiological color changes are indeed crucial for them to survive, either by protecting themselves from predators or by increasing their chances of feeding. Sometimes, they are also useful in courtship and mutual communications among individuals of the same species, leading to an increased rate of species survival. Such strategies are realized by complex mechanisms existing in the endocrine and/or nervous systems. Current studies further indicate that some paracrine factors such as endothelins (ETs) are involved in these processes. In this review, the elaborate mechanisms regulating chromatophores in these lovely aquatic animals are described.read more

Scototaxis as anxiety-like behavior in fish
Caio Maximino,Thiago Marques de Brito,Claudio Alberto Gellis de Mattos Dias,Amauri Gouveia,Silvio Morato +4 more
TL;DR: The scototaxis (dark/light preference) protocol is a behavioral model for fish that is being validated to assess the antianxiety effects of pharmacological agents and the behavioral effects of toxic substances, and to investigate the (epi)genetic bases of anxiety-related behavior.

The social zebrafish: behavioral responses to conspecific, heterospecific, and computer animated fish.
Cristina Saverino,Robert Gerlai +1 more
TL;DR: The results suggest that computerized stimulus presentation and automated behavioral quantification of zebrafish responses are feasible, which in turn implies that high throughput forward genetic mutation or drug screening will be possible in the analysis of social behavior with this model organism.

Morphological color changes in fish: Regulation of pigment cell density and morphology
TL;DR: In this article, morphological color changes are discussed as physiological phenomena involved in the balance between differentiation and apoptosis of chromatophores, and changes in their morphology are discussed.
